Problems solved by technology
Due to the influence of the gap and friction of the joint motion pair of the robot, it is difficult to improve the accuracy
In the prior art, there is a robot joint bearing without clearance. However, after tightening, although the clearance is small, after the friction force increases, the friction dead zone is difficult to overcome, and it is still difficult to improve the accuracy.

The invention relates to a rigid-flexible coupling modularized robot joint and application thereof. The rigid-flexible coupling modularized robot joint comprises a first shutdown part, a second shutdown part, bearings, a motor and a rigid-flexible coupling transmission shaft, wherein the rigid-flexible coupling transmission shaft is separately connected to the motor and the second joint part; themotor drives the second joint part to rotate through the rigid-flexible coupling transmission shaft; the bearings are separately arranged at the two ends of the rigid-flexible coupling transmission shaft; the rigid-flexible coupling transmission shaft is connected to the first joint part through the bearings; and the rigid-flexible coupling transmission shaft comprises a shaft part, an outer barrel and a flexible part, the shaft part is connected to the outer barrel through the flexible part. The modules can be quickly connected and separated, and each module is a unit which integrates drive and transmission; and different pedestals and different joints are assembled, so that a mechanical arm suitable for different working conditions can be constructed.
Description
technical field [0001] The invention relates to the technical field of industrial robots, and more specifically, to a rigid-flexible coupling modular robot joint and its application. Background technique [0002] As the application fields of industrial robots continue to expand, the working environment and working environment of industrial robots are also changing more and more widely. Traditional industrial robots can no longer keep up with the development of the market and industrial production. Traditional industrial robots are designed based on a single task. Once the design is finalized, the limitations of its own mechanical structure make its work and application fields very limited, which seriously restricts the application of industrial robots. At the beginning of the design of traditional industrial robots, its working environment and given tasks are known, and it is difficult for traditional industrial robots to adapt to the unpredictable environment unknown to hum...
